Okay. First impression: excellent. Some edits / options below.

[replacing the paragraph above]
**Conversion between proprietary data formats is imperfect** Changing
versions of proprietary software often breaks your files in subtle or
important ways. Sometimes proprietary software will allow you to
upgrade from the only most recent previous version. Open Source
software will often allow conversion from proprietary formats to Open
Formats that protect your file from future conversion problems.

It may take you some time to adapt to the improved performance, power
and security provided my many Open Source programs. While the tasks you
want to do may be the same, the tools are different and the methods may
change. Some changes will be subtle, like an icon that looks different
and some are substantial like a different name for a program. You see
similar changes in proprietary software when companies release major
updates, or when companies go out of business and you have to find a new

**Getting Help** You can get help for Open Source software in more ways
than with proprietary software. Some Open Source projects sell
commercial support that is the exact analogue of proprietary software
support services, except the Open Source projects actually have capable
staff. You may be in the habit of turning to a geeky friend, neighbour
or relative for unofficial technical support with proprietary software.
That is still an option with Open Source software and may allow you to
increase your list of geeky friends.
Most Open Source projects include a web site and mailing list archive of
previous problems and solutions related to their project. Those
references are available 24/7 and are generally excellent for questions
related to "How do I install ... or What are the steps to do ...?" Most
Open Source projects also include mailing lists and IRC chats of people
interested in the project. Participating on those on-line communities
will often provide immediate feedback and advice for problems you may

Some media companies believe that you don't have the right to use the
things that you buy from them in the ways that you want to use them.
Those backwards companies may try to restrict your rights by using
Digital Restrictions Management on the materials that they sell to you.
It's best to avoid those companies. When you choose to do business with
that sort of company, Open Source software will often allow you to
convert your media to Open Formats so that you may exercise your rights
on your purchased media.

Some companies build hardware that supports Open Source software better
than others. Higher quality hardware with full support for Open Source
software is not necessarily more expensive than low quality, proprietary
hardware. Caveat emptor applies to computers as well as everything

You'll find that most Open Source software "Just Works" and you won't
have to think about it. But some Open Source projects will warrant more
of your attention because you are a power-user or you have a special
interest or expertise in the subject matter. You can participate in an
Open Source project in ways that are not possible with proprietary
software by joining the community.
With proprietary software you may choose to make demands on the
proprietary software vendor and you may see a reply from them. Or
When you join an Open Source community you communicate with other
interested users, subject matter experts, consultants and often the
software developers of the software. Without a commercial support
contract the need to scream and stomp about your contract and fees is
gone, so you can relax and have a grown-up conversation with other
interested and interesting people. Often finding concerned, expert
assistance is as easy as asking politely on IRC or email, with a
description of the challenge you've run into.
